Gigabyte X670 AORUS ELITE AX - Do I need to plug 2x 8 pin connectors to power the CPU (ATX power)?

Go to solution Solved by mariushm,

A single 8 pin connector is rated for up to around 300-320 watts. 

The 7950x can consume up to 250-260 watts, if you cool it properly. If you try to overclock it, it will consume even more. 

 

While technically this 250 watts  is below the rating of the single 8 pin CPU connector, it's highly recommended to use both cables and connectors because you'll reduce the "stress" on the connectors and headers on the motherboard - the connectors and headers will heat less, and there's gonna be less losses in the wires between the power supply and the motherboard.

 

You don't "overvolt" the processor by connecting more wires. You just add more wires, meaning each wire and each pin in the connectors and headers has to carry less power, which means happier components.

 

You have 6 (SIX) headers on the motherboard   power supply, the three above the text saying 6+2 PCI-E & 4+4 CPU , and the three under it.  They can be used either for video cards, or to power CPUs.  You don't need to use exactly those two you circled. In fact, it would probably be just a very very tiny bit better to have one cable plugged a  bit further away from the first cable - leave one column of headers empty on the power supply. 

 

Hi Guys,

 

Today I bought a 7950x and the above titled motherboard. I have a Corsair HX1000 Platinum Modular 1000W Power Supply.

Question 1. Do I need to plug in a 2x4 pin connector to both the 8pin ATX power ports? Or do I just need to power one of the 8 pin ports?

Question 2. Will individual 2x4 pin cables work?

Plug in it all, why did you buy all that expensive shit the day of release and want to cut corners?

 

Your PSU should have the right connectors. If not, get a different one.

Sorry I should have elaborated, I am not trying to cheap out I was just worried I would overvolt the motherboard - with the assumption that they are two separate ports and I should only use one of them since I thought it only needs 12v to the CPU.

 

Would two separate 2x4 pin connectors work from my PSU circled below?

Just want to make sure I am plugging it in correctly.

 

Thanks for helping!

Thank you makes perfect sense now.
